# Taiwan Han Kuang 42 exercise > Live situation record from CLSTR: https://clstr.news/situations/taiwan-han-kuang-42-exercise > Updated: 2026-08-04T16:01:00.000Z. Sources: 17. Developments: 3. The Republic of China Armed Forces continued the Han Kuang 42 live‑fire drill that began on 5 August 2026, a ten‑day, ten‑night maneuver that for the first time incorporated a pre‑emptive blockage scenario on the newly opened Danjiang Bridge. The exercise emphasized multi‑domain denial and resilient defence, integrating land, sea, air, cyber and electromagnetic capabilities, AI‑driven command systems, unmanned platforms and precision mining. About 5,000 reservists from the Taipei and 137th infantry brigades were mobilised, alongside a full brigade from the north and one from the south. New elements included operational use of M1A2T main battle tanks, a newly formed Coastal Operations Command with radar and anti‑ship missile units, and a 30‑minute network‑slowdown test to assess communications resilience. A U.S‑inspired “back‑brief” verification method was fielded to ensure command‑and‑control synchronization. The drill also simulated the wartime relocation of a major arsenal, mobilised civilian factories, and featured fighter‑jet dispersals and emergency naval deployments. It progressed through phases of deployment, force protection, anti‑landing, deep‑defence and sustained operations, aiming to prepare for possible Chinese attempts to paralyse command centres, ports, logistics and defence‑industry sites. Additional focus areas covered joint air‑to‑sea operations, medical support, civilian‑military coordination for town‑level resilience drills, an “embedded reporter” programme and updated rules of engagement. ## Claims - Taiwan began the 10‑day annual Han Kuang military drill on 5 August 2024.
